Overview of Viscosity and Its Characterization

This technique allows the quantitative characterization of viscoeleastic properties. That is, it allows quantifying the ability of a material to store and/or dissipate mechanical energy of a specific duration. These properties correlate with such traditional empirical tests as hardness, strength, yield point, impact, and some viscosity tests. Because of the wide range of operational modes, geometries, and test methods, DMT can only treated here in a brief overview. Figure 7-23 shows a commercially available DMT instrument.
